Many people have at least one body quirk they would happily get rid of, such as hairy toes, smelly feet or excessive sweating. However, according to Rachel Jones, Pharmacy Superintendent at Superdrug, some of these traits may actually be signs that important systems are functioning as they should.
Rachel said: "While persistent or sudden changes should always be checked by a healthcare professional, many common bodily functions that people find embarrassing can actually be completely normal and, in some cases, indicate that the body is working exactly as it should."
Hairy toes
Toe hair is often a cosmetic concern, but its presence or absence alone is not a reliable measure of circulation. Rachel Jones said: "Hair growth on the feet is influenced by a range of factors, including genetics, age and hormones, so the amount of hair varies considerably from person to person. On its own, having hairy toes doesn't necessarily tell us anything definitive about circulation."
She added: "However, a noticeable change, such as a sudden loss of hair on the feet or lower legs alongside symptoms like persistent cold feet, pain when walking, numbness, slow-healing wounds or changes in skin colour could be a sign of an underlying circulation problem. If these symptoms occur, it's important to seek advice from a healthcare professional so they can assess the cause."
Ear wax
Ear wax is often seen as dirty, but it plays an important protective role. Rachel said: "Ear wax acts as the ear's natural defence system. It helps trap dust, dirt and bacteria before they can reach the inner ear and also helps keep the ear canal moisturised."
While excessive wax build-up can cause hearing difficulties or discomfort, Rachel advises against regularly using cotton buds, as they can push wax further into the ear canal.
Passing wind
Passing wind is an important sign that the digestive system is functioning normally. Rachel said: "Gas is a natural by product of digestion. In fact, passing wind is generally a sign that your digestive system and gut bacteria are doing their job. Foods high in fibre, such as vegetables, beans and wholegrains, can often increase gas production because they're supporting healthy digestion."
While occasional wind is usually nothing to worry about, Rachel says significant changes should be investigated. She added: "Many people feel embarrassed talking about digestive health, but understanding what's normal for your body is important."
Smelly feet
Foot odour is common in warmer months, but the smell is not caused by sweat. Rachel said: "Sweat is actually odourless. The smell develops when sweat mixes with naturally occurring bacteria on the skin. While sweating is unpleasant, it often indicates that the body's temperature regulation system is functioning normally."
Sweating
Sweating is one of the body's most important cooling mechanisms. Rachel said: "Sweating is how the body regulates its temperature and prevents overheating. Without it, we wouldn't be able to cool ourselves down effectively." However, excessive sweating that occurs regardless of temperature or activity may indicate hyperhidrosis, a condition affecting an estimated 1 million people in the UK.
Rachel said: "Social media and beauty standards often make people feel like normal bodily functions are something to hide or fix. In reality, many of these things are signs that our bodies are doing exactly what they're designed to do. Understanding what's normal can help people feel more confident about their health, while also recognising when a change might be worth getting checked out."
